How can a debugger be utilized in PHP to streamline the debugging process and reduce the need for echo statements?

To streamline the debugging process and reduce the need for echo statements in PHP, a debugger can be utilized. Debuggers allow developers to set breakpoints, step through code line by line, inspect variables, and track the flow of execution. This can help identify and fix bugs more efficiently than using echo statements.

// Example code using Xdebug debugger
// Install Xdebug extension in PHP and configure IDE for debugging

// Set a breakpoint in the code
$x = 10;
$y = 20;
$sum = $x + $y;

// Start the debugger in your IDE and step through the code
// Inspect variables like $x, $y, and $sum to track their values
// Fix any issues identified during debugging
